Description

  The present invention relates to a voice guidance device that is designed for the safety of people with visual disabilities, in particular, by a mechanism in which a sensor senses a change in a set distance when a user touches a handrail Braille.

  As a conventional technology, a voice guidance information transmitter composed of a voice recording / playback LSI, a voice memory, a microphone, a data transmitter, operation switches, a status display unit, and other electronic components (crystal oscillator, resistor, capacitor, etc.) And a voice guidance system using a radio widely used on the receiver side. (See Patent Document 1)

In addition, as another conventional technique, a detection electrode, a detection circuit connected to the detection electrode, and a control circuit that performs voice guidance by inputting a detection signal of the detection circuit are provided. There is a voice guidance device characterized in that when a finger or the like approaches or comes into contact, the capacitance between the detection electrode and the ground changes, and the detection signal is input to the control circuit. (See Patent Document 2)
Japanese Patent Laid-Open No. 10-224885 JP 2001-166722 A

  The former simply receives voice guidance information by radio, does not have an energy saving detection circuit, and does not have a guidance display board, so there is no visual information especially for a healthy person. .

  In addition, the latter requires a great amount of time and labor for construction, and is designed so that it does not operate unless it directly contacts the detection electrode, and an error may occur.

  The present invention has been made in view of the above-described problems, and its purpose is to detect a sensor by placing a hand near a required position and listen to necessary information on a speaker and / or FM radio. A voice guidance device is provided.

As a means for achieving the above object, the present invention comprises a detection circuit that senses a change in a set distance and a sound circuit through which sound flows.
Further, a guidance display board is provided.
The detection circuit uses an infrared sensor or an ultrasonic sensor.
In addition, infrared rays or ultrasonic waves transmitted from the detection circuit are intermittently transmitted.
Further, the audio circuit is set so as to be selectable from a speaker and / or an FM circuit that plays audio using FM radio waves.
Furthermore, the power source is a dry battery.

1) Because it is composed of a detection circuit that senses changes in the set distance and a voice circuit through which sound flows, the sensor reacts and records when a hand is placed near the required position (for example, a handrail on a staircase). Since audio can be played, information can be provided reliably without operating errors.
2) By providing a guidance display board, various information can be provided to healthy persons.
3) By using an infrared sensor or an ultrasonic sensor, it can be selected depending on the location and surrounding conditions, such as using an ultrasonic sensor in a bright outdoor place.
4) It is possible to suppress the exhaustion of the battery (battery or the like) as much as possible by transmitting infrared rays or ultrasonic waves to be transmitted intermittently (for example, at intervals of 1 second).
5) Since the audio circuit can be heard by a speaker and / or FM radio waves (FM radio), it can be changed depending on the place and purpose.
6) Since it is a dry cell type, it can be used even in places where there is no power source (100V, etc.).

BEST MODE FOR CARRYING OUT THE INVENTION

Reference numeral 1 denotes a voice guidance device.
Reference numeral 2 denotes a case made of synthetic resin or the like, which basically has a waterproof function.
Reference numeral 3 denotes a detection circuit for detecting a change in the set distance, which is linked to the infrared sensor or the ultrasonic sensor 3a, and reacts when a hand or the like enters within a set fixed distance.
In addition, infrared rays or ultrasonic waves to be transmitted are transmitted at intervals of about 1 second.
Reference numeral 4 denotes an audio circuit through which sound flows and is interlocked with the speaker 4a.
Reference numeral 5 denotes an FM circuit that transmits the sound data of the sound circuit 4 by FM radio waves, and transmits the data at a short distance (within 10 m) by the antenna 5a.
A memory card 6 transmits audio data to the audio circuit 4 and stores various messages.
Reference numeral 7 denotes a power source, which has a dry battery specification, but may be 100V.
Reference numeral 8 denotes a segment display for displaying an internal set value or an error number.
Reference numeral 9 denotes a cover of the case 2 provided with a guide display board 9a suitable for the place of use.
Reference numeral 10 denotes an audio data switching unit for switching audio data settings.

An example of use of the voice guidance device 1 configured as described above will be described below.
For example, when attaching to the stairs of the platform of a station, the Braille nameplate MB for handrails is attached to the upper part JB and the lower part KB of the handrail T provided on the side wall S of the stairs K.
Next, a voice guidance device is provided at a required position above the handrail Braille nameplate MB. (Audio data switching unit 10 selects audio data.)

In this state, when the visually handicapped person S tries to go up the stairs and puts his hand at a position where he touches the handrail Braille nameplate MB, the sensor 3a reacts, a voice (message) flows from the speaker 4a, and information around the stairs is obtained. Can be obtained.
If necessary, the FM circuit 5 can listen to information on the FM radio R via the antenna 5a.

The upper voice guidance device 1 is also used in the same manner.
The set distance can be changed depending on the mounting location (position).
The voice (message) may be determined as needed without any particular limitation.
The display content of the guidance display board may be determined as necessary.
The intermittent transmission interval of infrared or ultrasonic waves shall be determined according to the frequency of use.
When listening to the sound (message) on the speaker and / or FM radio, whether to use one or both at the same time may be selected as necessary.
In addition, it is also considered to use a solar power source.
